Liquid solder is generally considered for industrial usage. Now a days, it is becoming a household need as well. Hence, it is only right that you know the basics of how to use a liquid solder. It is used for soldering purposes. Soldering is a process to bond two metal surfaces together and these liquid solders are one of the user agents that helps us achieve it. They are bound to be really strong adhesives for they need to join metals.

Let’s Go Through These Steps To Learn How To Use a Liquid Solder

Step 1: Get your tool kit ready.

Soldering manuals prescribe specific paraphernalia. So, the first step should be to get these things ready. Choose your liquid solder flux. Solder paste in tubes works as a better liquid solder for electronics. Those available in cans are also widely used. However, that works for where the larger surface areas need soldering.

Step 2: Check the surfaces to be soldered.

The second step is to make sure that the chosen surfaces have been properly cleaned and smoothed. Remove all possible obstacles that could hinder the process of soldering. And last but not the least, ensure that the surfaces and their material contain no moisture.

Step 3: How to Apply.

Be prepared with your adhesive. You should take due precautions at this stage. Never touch the solder paste. Melted soldering flux is bound to be hot. Even tube and can users need to take care of. Can users use a stick to apply the adhesive, probably a wooden one? The application of liquid solder flux must be done on both the surfaces.

Step 4: Maintenance right after application.

This is an important step to ensure that the result is foolproof. It ensures that the soldering attains the required/maximum adhesive strength. The soldered point should not be disturbed. The slightest disturbance can lead to various effects on the soldered point. It can even undergo complete rupture if the disturbance is too unbearable. So it is better to leave the soldered surfaces undisturbed. The basic norm is to not disturb the bonded surfaces for the next 24 hours. It can vary according to the material of the joined surfaces, quality of the liquid solder and the surrounding temperature. Also, it is advised not to use water or any other liquid for cooling.

Step 5: Desoldering

Learning about soldering is incomplete without learning desoldering. It is the process of removal of solder. Though it is more complicated, it can be done easily in some cases. Acetone, a readily available product in the market, can help to desolder. You can apply acetone to the joint and let the effect take place.


The market is flooded with an extensive range of liquid solder flux.O’Reilly is one of the popular brands among customers. They manufacture all kinds of soldering equipment along with liquid solder flux. They are even available online. The prices of these products are within an affordable range.

P.S. – DIY. Yes, you can always make your own liquid solder flux for electronic devices. But the first master how to use liquid solder.
